Our take
Kraken is one of the world's leading and longest-standing cryptocurrency exchanges, known for its focus on transparency and security. The platform offers trading across a wide range of digital assets and fiat currencies, including USD, EUR, and CAD, and serves millions of users globally. Consistently rated as one of the most trusted and secure exchanges in the industry, Kraken has built a reputation on reliability, users protection, and a commitment to its proof-of-reserves verification that allows clients to independently confirm their holdings.
Kraken allows users to trade and invest in spot and derivatives markets, as well as participate in staking, custody, and tokenized asset products. It was also among the first exchanges to undergo a cryptographically verifiable proof-of-reserves audit and continues to lead with innovations such as tokenized US stocks ("xStocks") for non-US customers and expanded institutional services. Alongside this, the company's offerings are designed to make digital finance more accessible and complaint while supporting traders, investors, and enterprises navigating the fast-evolving crypto landscape.
On top of this success, Kraken reported a standout performance in the third quarter of 2025 - doubling its revenue year-on-year to $648M and boosting quarterly profit margins to nearly 28%. Trading volumes climbed to $562B, while assets on the platform rose to $59B, emphasizing the exchange's growth and strong customer confidence. Having expanded its product suite, strengthened its institutional reach, and invested in governance and compliance, Kraken is now in a position for continued expansion (and, potentially, a future public listing), as one of the most resilient and respected names in the global crypto market.
